Loosen the dependency versions in Cargo.toml

[ghost]

I don't think they were ever intended to be specific to the patch version but were accidentally made so in a1faa7c.

This upgrades docopt.rs to a version that supports typo suggestions for flags:

$ cargo build --jobz 64
Unknown flag: '--jobz'. Did you mean '--jobs'?

Closes #1546.

I was under the impression that a 0.x.y dependency is satisfied by any 0.x.z with z >= y.

I agree with @huonw that the tweaks to Cargo.toml aren't strictly necessary, but it's fine to have them anyway!

Unfortunately it looks like we can't upgrade Rust just yet due to a recently introduced bug in process spawning: rust-lang/rust#24873

@alexcrichton I see, thanks for investigating!

☔ The latest upstream changes (presumably #1564) made this pull request unmergeable. Please resolve the merge conflicts.

Ok I picked up a bunch of updates as part of #1564 (needed to update curl which needed to update openssl), but I wasn't able to update everything. As rust-lang/rust#24873 just landed as well tonight's nightly should be the next available which can build Cargo!

This is probably ready for a rebase now
